Omron D4C-4332 Limit Switch
Omron D4C-4332 is a general-purpose limit switch with a sealed stainless steel roller plunger for reliable machine position detection. The rolling actuator suits cams, slides, conveyors, and moving workpieces, while the sealed construction supports use around factory contaminants. Its SPDT contact form is configured for microload circuits, making it suitable where low-current position signals are required rather than higher switching loads. IP67 protection and operation from -10 to 70°C support industrial environments. The D4C-4332 belongs to the D4C Series within the microload roller plunger switch range from Omron industrial control products for precise machine travel and position sensing.

The Omron D4C-4332 Limit Switch uses a sealed roller plunger with a 12 mm × 4.4 mm sintered stainless steel roller for repeatable mechanical position detection. The rolling actuator suits cams, slides, conveyors, and moving workpieces that pass across the sensing point, while the sealed construction helps protect the actuator mechanism in demanding factory environments. Its SPDT contact form provides changeover switching for microload circuits rated at 0.1 A at 125 VAC and 0.1 A at 30 VDC. IP67 protection supports installations exposed to dust, water, and industrial contaminants, while operation from -10 to 70°C suits common machine environments.
D4C-4332 provides at least 10 million mechanical operations and 200,000 electrical operations, supporting frequent switching in automated equipment. Contact resistance is 400 mΩ maximum, and the switch withstands destructive shock up to 1,000 m/s² and malfunction shock up to 500 m/s². Relative humidity can range from 35 to 95%, and an earth wire supports grounded installation. These characteristics make the model suitable where sealed roller actuation, microload switching, and compact D4C construction are required for travel or end-position sensing in production machinery reliably. For another D4C model with a sealed roller plunger and general-load configuration, see the D4C-3232 model.
